UNITED STATES PATENT JOHN WV. POINDEXTER, OF OYNTHIANA, KENTUCKY.

SEED-TUBE FOR GRAlN DRILLS.

SPECIFICATION forming part of Letters Patent No. 682,341, dated September 10, 1.901. Application filed May 3, 1901. Serial No. 58,660. (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. POINDEXTER, a citizen of the United States, residing at Cynthiana, in the county of Harrison and State of Kentucky, have invented certain new and useful Improvements in Seed-Tubes for Grain= Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

The object of my invention is to provide a method of connection between the seed-cup or funnel and the coiled-wire tube by interposing a flexible section between said seedcup and coiled-wire tube in such a manner that the tube will have ample room for lateral movement without twisting or springing it out of shape.

The novelty of my invention will be hereinafter more fully set forth, and specifically pointed out in the claims.

In the accompanying drawing, which is a side elevation of a part of an ordinary seedcup of a grain-drill, boot, or hopper of the ordinary or any suitable construction and my improved flexible tube, all shown in their relative positions, A is the seed-cup, having the usual receiver 13 hinged thereto, as at b. To the lower end of the receiver B is secured in any suitable manner, as by a wire 0, a flexible tube (1, preferably of canvas or heavy duck or rubber or any othersuitable flexible material. This tube Cis about six inches long and is slightly tapered toward its lower end. A coiled-wire tube D, which is also slightly tapered, is dropped into the flexible tube 0, it being slightly larger at the upper end than the tube 0 is at its lower end, so that when the tube D is pulled downward it looks itself into the lower end of the tube C, as will be readily understood. The lower end of the tube D extends into the upper end of the boot E for the purpose of conducting the grain into said boot, from thence to be dropped into the ground. Heretofore in constructing tubes of this character they have been rigidly at tached to the receiver B, and when the boot E in passing over an obstruction is raised, as shown by the dotted lines, the tube D would be twisted at its upper end in such a way that it would not resume its former shape, but by continual twisting would grad ually become so sprung that the grain, and more especially fertilizer, would not pass freely through said tube, while in my present construction when the boot is raised the flexible material will give, as shown by the dotted lines, and when the boot resumes its former position the weight of the wire tube D will be sufflcient to cause it to resume its normal shape, so that the interior of the tube will be left perfectly free and the grain be permitted to passthrough without the lia bility of choking or clogging in the tube.

While I prefer to use acoiled-wire tube, as

I have shown, still it is obvious that any other form of tube may be used without departing from the spirit of my invention.

Having thus fully described my invention, I claim- 1. In a grain-drill tube of the character described, the combination of an upper flexible portion suitably secured to the grain-receiver, and a lower portion composed of coiled wire secured to the upper flexible portion and extending into the upper end of the boot, substantially as described.

2. In a grain-drill tube of the character described, the combination of an upper flexible portion composed of canvas or heavy duck suitably secured to the grain-receiver, and a lower portion composed of coiled wire secured to the upper flexible portion and extending into the upper end of the boot, substantially as described.
